I did the same thing. one boringly rainy day while playing endless marathon, I used the rotate/climb method to see how far I could go. after realizing I could pretty much go on forever using it, so I tried to max out the line and level counters. after that, I just let it go since my thumbs were falling apart. although it does make it easy, it doesn't work with every piece, every time. (Square pieces = death in high levels)
good to see i'm not the only person who really was that curious about maxing out those meters...
